Chevron Oronite announced recently that it has introduced PARATONE® 8900E, an enhanced viscosity modifier which offers excellent low-temperature performance, superior thickening efficiency, and extended shear stability. PARATONE® 8900E is designed for use in formulating passenger car and heavy-duty engine oils, other multi-grade crankcase oils, power transmission fluids and industrial engine oils.

“Our polymer scientists took a fresh look at the building blocks of PARATONE® 8900, its detailed molecular structure, and how each of its key attributes influence the overall performance of finished lubricants,” said Bill Paschal, Global Product Manager, Viscosity Index Improvers, Chevron Oronite. “After several years of research and testing, we have identified and implemented small, precise adjustments in the polymer molecule, resulting in a product that delivers robust low-temperature performance while providing the excellent thickening efficiency and extended shear stability our customers have come to expect and rely upon with PARATONE® 8900.

Oronite anticipates that self-dissolving viscosity modifier customers will want to transition to PARATONE® 8900E due to the benefits of the enhanced product. In addition to excellent low-temperature performance, outstanding thickening efficiency, and extended shear stability, Chevron Oronite explained that PARATONE® 8900E also works well with numerous Pour Point Depressants, and will provide improved formulating flexibility for lubricant designers. “We believe PARATONE® 8900E offers exceptional value by delivering strong performance at very competitive treat rates,” Paschal added.

Oronite will also incorporate PARATONE® 8900E into its portfolio of concentrate products in the coming months.
